A Quarter Of Nursing Home Residents Are Colonized With Drug Resistant Bacteria

A quarter of nursing home residents are colonized with drug-resistant bacteria

The significant presence of multidrug-resistant gram-negative bacteria (MDR-GNB), such as E. coli, among nursing home residents demonstrates the need for heightened infection control prevention and control measures in nursing homes, according to a meta-analysis published in the American Journal of Infection Control, the official journal of the Association for Professionals in Infection Control and Epidemiology (APIC).

The systematic literature review and meta-analysis, conducted by Sainfer Aliyu, MPhil, MSEd, MHPM, BSN, RN, and others at the Columbia University School of Nursing, found the prevalence of MDR-GNB colonization among sampled nursing home residents ranged from 11.2 percent to 59.1 percent, with a pooled average of 27 percent. Researchers also found that nine of the 12 studies involved identified specific factors that are associated with increased MDR-GNB colonization risk, including advanced age, gender, comorbid chronic diseases, history of recurrent hospitalization, increased interaction with healthcare workers, frequent antimicrobial exposure, delayed initiation of effective antibiotic therapy, presence of medical devices, decreased functional status, advanced dementia, nonambulatory status, fecal incontinence, severe sepsis present on admission, and residency in a long-term care facility.

The study is thought to be the first systematic review and meta-analysis of its kind, and should raise concerns among infection control professionals and nursing…
